The Plone Logo

Plone® Logo Pack

The Plone® logo is a registered trademark of the Plone Foundation.

Projects and companies that use Plone are encouraged to incorporate the Plone logo on their websites, brochures, packaging, and elsewhere to indicate suitability for use with Plone or implementation using Plone.

However, you are not allowed to use the logo or its likeness as a company logo or for any other commercial purpose without permission from the Plone Foundation. Regional Plone User Groups have explicit permission to use the logo in their promotional materials, t-shirts etc, as long as they don't make any direct profit from it.

All images are optimized (using OptiPNG and pngcrush, see below) and use alpha transparency.

The PNGs use an 8-bit palette to degrade gracefully without PNG hacks even in Internet Explorer 6 (see how). However, the antialiasing is rough on the edges, so we recommend the version with white background instead of transparent if you need it to look perfect in IE6. We include a pre-rendered version with white background.

The images has been compressed and stripped of any color profiles (see why)

You can easily use the logo on backgrounds that are not white, and get great antialiasing.

Guidelines for Use

The Plone logo is a worldwide registered trademark of the Plone Foundation, which is responsible for defending against any damaging or confusing uses of the trademark. For guidelines on how to use and not use the logo, consult the Plone Logo Usage Guidelines.

In general, we want the logo to be used as widely as possible to promote Plone and the Plone community. Derivative versions of the Plone logo are generally prohibited, as they dilute Plone's brand identity. However, please contact the IP committee via email if you have any questions.

T-shirts and other Merchandise

Making your own shirts with the Plone logo is OK, as long as the profits are donated to the Plone Foundation. Please seek permission from the Plone Foundation if you are planning to sell merchandise that shows the Plone logo.

History

The official colors were off in the prerelease version because of color profile issues. The correct colors are: Web: #0083be, Pantone: 7461C

iPhone and Mac OS X style icons added.

Favicon for browser use (bookmarks etc) was added. The default favicon.ico file has two sizes embedded: 16px and 32px. There are two additional files available that includes 48px and 64px icons too, but be aware that these are larger downloads, and might not be a sensible default. They are included for future use, when default sizes might be different.

The registered trademark symbol was moved slightly to improve balance.

The 16px logo has been hand-tweaked for increased legibility.

All PNGs have had their gamma and color profiles removed by running pngcrush -rem gAMA -rem cHRM -rem iCCP -rem sRGB and then further optimized by running optipng -o7.

v0.9 (Feb 4, 2008): Prerelease version of the logo refresh.
